🔍 Key Concepts

• Propeller pitch as the theoretical distance advanced in one revolution (in feet) • How to compute theoretical distance per day from pitch and revolutions • Meaning of 9% positive slip and how it reduces the actual distance run

💭 Think About

• First, ignore slip and find how many feet the ship would travel in one day if it advanced exactly one pitch per revolution. What is the formula? • Next, adjust that distance for 9% positive slip. Does positive slip make the actual distance more or less than the theoretical distance? By what factor? • Finally, convert the corrected distance from feet to miles (remember how many feet are in a nautical mile or a statute mile, depending on what you think the problem is asking for), then compare with the choices.

✅ Before You Answer

• Be sure you multiply pitch × revolutions per day before applying slip. • Apply slip in the correct direction: positive slip reduces actual distance from the theoretical distance. • Confirm your final units: you should have miles per day, not feet or nautical miles, before comparing to the answer choices.
